Verified answer

Answer:

50 km/hr²

Explanation:

We can use the formula for acceleration:

a = (v - u) / t

where:

a = acceleration

v = final velocity = 50 km/hr

u = initial velocity = 0 km/hr (since the train starts from a stationary position)

t = time taken to reach the final velocity = 60 minutes = 1 hour

Substituting the values in the formula, we get:

a = (50 - 0) / 1

a = 50 km/hr²

Therefore, the acceleration of the train is 50 km/hr².

Answer:

Explanation:

Initial speed, u = 0 m/S^2

Final velocity v  = 50 km/hr   => 50*5/18 =>  13.8 m/s    [ 1km/hr = 1 * 5/18 m/s]

Time t = 60 min => 3600 sec

Formula:-

v = u + at ( where 'a' is the acceleration )

13.8 = 0 + a(3600)

a= 13.8/3600

a= 3.83* 10^-3
